The biophysical profile involves assessment of fetal well-being with a combination of the nonstress test and four ultrasonographic parameters (amniotic fluid volume, respiratory movements, body movements and muscle tone). Options include the nonstress test, the biophysical profile and an oxytocin (Pitocin) challenge test. In any case, antenatal testing should be instituted. Although not of proven benefit, bed rest may maximize uterine blood flow. General management measures include treatment of maternal disease, cessation of substance abuse, good nutrition and institution of bed rest. The fetus should be monitored continuously during labor to minimize fetal hypoxia. Preterm delivery is indicated if the fetus shows evidence of abnormal function on biophysical profile testing. General management measures include treatment of maternal disease, good nutrition and institution of bed rest.
LOW AMNIOTIC FLUID AT 20 WEEK ULTRASOUND SERIAL
Serial ultrasonograms are important for monitoring growth restriction, and management must be individualized. A lag in fundal height of 4 cm or more suggests IUGR. Growth restriction is classified as symmetric and asymmetric. Ultrasound biometry is the gold standard for assessment of fetal size and the amount of amniotic fluid. Accurate dating early in pregnancy is essential for a diagnosis of IUGR. Certain pregnancies are at high risk for growth restriction, although a substantial percentage of cases occur in the general obstetric population.
Identification of IUGR is crucial because proper evaluation and management can result in a favorable outcome. Intrauterine growth restriction (IUGR) is a common diagnosis in obstetrics and carries an increased risk of perinatal mortality and morbidity.
